@tmonz:matrix.orgtmonzDepends a lot on the details21:01:23
@tmonz:matrix.orgtmonz But see the stuff from Bristol here

@tmonz:matrix.orgtmonzWith 2 photon coincidence rate in the kHz domain21:02:01
@cbt-7y9:matrix.uni-hannover.deHendrik WeimerThe all-to-all connectivity of trapped ions is somewhat less relevant if you have a device containing many computing registers and relatively slow shuttling operations between them. I guess then you end up with similar locality constraints. Actually, some of the proposed architectures look very similar to what we discussed for Rydberg atoms some time ago. And there's been a pretty cool paper by Misha Lukin recently, where they've shown shuttling in their tweezers combined with Rydberg gates. With Rydberg atoms, I see the bigger challenge in the gate fidelities, especially concerning the fundamental limitations coming from the finite lifetime of the Rydberg state.21:28:40
@tmonz:matrix.orgtmonzI am less concerned about the lifetime . You can encode in the ground state and use the Rydberg only temporarily for the gates22:01:48

@cbt-7y9:matrix.uni-hannover.deHendrik WeimerSure, but if you want 10^-4 gate errors and have lifetimes in the tens of microseconds, you can imagine what that means in terms of the required laser intensities. That's tough.09:19:32
@tmonz:matrix.orgtmonzIt was never easy ;) Intensity is likely easier to handle than getting an SLM that can stand those powers in the first place 11:55:41
@cbt-7y9:matrix.uni-hannover.deHendrik Weimeryeah, makes sense16:04:43
@cbt-7y9:matrix.uni-hannover.deHendrik Weimer* yeah, makes sense experimental details 😉16:15:07

@michelle:privacytech.xyzmichelle 1ethanhansenis on a roll lately - many holiday episodes released and there is interesting content there for everyone I think.

Thanks! Definitely helps I had all these interviews recorded back in like the summer so I kinda needed to get them out 😬

@towynlin:matrix.orgtowynlin Speaking of which, I'm trying to get 1ethanhansen 's Zero to QC Hero spreadsheet from the torrent file available at https://gitlab.com/1ethanhansen/zero-to-qc-hero, but I guess I'm not seeing any peers with the file because it's not downloading. Anybody out there have it and can fire up their torrent client? 19:48:00

Go ahead and give it another shot It's possible my university is blocking me but I should he seeding rn

Verified that I can get LibreOffice via the torrent, but still no luck with yours. So, yeah, maybe blocked on your end.

@1ethanhansen:matrix.org1ethanhansenWell that sucks Too many leeches, i've uploaded that torrent 100+ times21:21:25
